The invention relates to an auxiliary transmission, a main transmission and a vehicle, the auxiliary transmission comprises an intermediate shaft, one end of the intermediate shaft is in spline connection with an output shaft, and the outer wall of the other end of the intermediate shaft is sleeved with a second input gear; the planetary gear shaft is arranged on the outer wall of the intermediate shaft in a sleeving mode, one end of the planetary gear shaft is meshed with a planet carrier assembly, and the outer wall of the other end of the planetary gear shaft is sleeved with a first input gear; one end of the synchronizer assembly is in spline connection with the output shaft, the other end of the synchronizer assembly is in spline connection with the planet carrier assembly, and the synchronizer assembly is used for power connection or power disconnection of the planet carrier assembly and the intermediate shaft. The problems that a planetary gear assembly (a planetary gear shaft and a planetary carrier assembly) of a traditional auxiliary transmission is always in a running state, abrasion of a planetary gear is accelerated, the service life is shortened, the transmission efficiency is reduced, and frequent maintenance and replacement of parts are needed when the traditional auxiliary transmission works in a speed reduction output mode or a direct output mode can be solved.

    本申请涉及一种副变速器、主变速器及车辆,其包括:中间轴,所述中间轴的一端花键连接有输出轴,且其另一端外壁套设有第二输入齿轮;行星齿轮轴,所述行星齿轮轴套设于所述中间轴的外壁,所述行星齿轮轴的一端啮合有行星架总成,且其另一端外壁套设有第一输入齿轮;同步器总成,所述同步器总成的一端与所述输出轴花键连接,且另一端与所述行星架总成花键连接,所述同步器总成用于所述行星架总成和所述中间轴的动力连接或动力断连。可以避免传统副变速器无论减速输出或直接输出工作时,其行星齿轮总成(行星齿轮轴和行星架总成)始终处于运转状态,加速行星齿轮的磨损、缩短使用寿命、降低传动效率、需要频繁维护和更换部件的问题。
